Phase Angle as a Marker of Muscle Damage, Muscle Fatigue and Inflammation, After Eccentric Exercise

Universidad Francisco de Vitoria28 enrolled

Overview

The purpose of this study will be to assess the effectiveness of bioimpedance device (BIA) as a safe, rapid, and non-invasive method of analyzing muscle damage induced by high intensity induced eccentric exercise as an alternative measurement tool against traditional assessment methods. A sample of 28 sedentary subjects will be recruited, all participants will perform an eccentric exercise protocol. Measurements will be done before performing the exercise protocol, immediately after finishing the protocol, 3h after the end of the exercise protocol, 24h after the end of the exercise protocol and 48h after the end of the exercise protocol. The variables analyzed in all subjects will be phase angle, creatinkinase, jumping strength, VAS scale, white blood count cell, quadriceps muscle thickness, Borg scale and anxiety and depression questionnaires.

Primary Outcomes

Phase angle

The phase angle, which is measured via bioelectrical impedance analysis (BIA), InBody 770 ,is a clinically important bioimpedance parameter used for nutritional assessment and evaluating the risk of various diseases. The phase angle was calculated automatically by the BIA device from these two components according to the following formula: phase angle (°) = (reactance/resistance) × (180°/π).
